Native-Oxide-Defined Semiconductor Quantum Well Lasers and Optoelectronic Devices: Al-Based III-V Native Oxides
Abstract
The study and use of Al-based III-V native oxide in quantum well heterostructure (QWH) devices has been pioneered in this project, and since the time of its introduction (1990) has grown into an international activity. An almost all-oxide enclosed microcavity laser and LED have been realized In the latter stages of this project. By employing a tunnel junction contact as a mechanism to invert lateral (edgewise) electron current into injection hole current (and thus accomplish laterally offset carrier injection), we have demonstrated oxide-confined edge emitter and vertical cavity surface emitting lasers (VCSELs) driven entirely with lateral electron currents, and thus with reduced resistive losses in spite of the offset current source. This is potentially important for optoelectronic IC development. The use of the Al-based III-IV native oxide to thwart hydrolyzation and increase device reliability has been demonstrated.
